confused 2002 3.8L Mustang Heat Problem

I have a 2002 3.8L Mustang and I just replaced the radiator this past weekend. Now the heat all of a sudden stopped working. When I turned it on, it was cold air blowing out then when it finally heated up it was only warm for a min or so then it went right back to freezing cold! Any ideas what could be wrong? I dont know much about cars and im completely clueless! Any help would be greatly appreciated!! Thanks!!

Re: 2002 3.8L Mustang Heat Problem

car still cooling fine after swap? no leakes in pass. floor ? there is a eleitric switch which connects in a line from somewhere off raditor and goes to your heator cord under your dash along with a return line which comppletes a circle. a fan blows heat transfered from the radiator thru a sm radiator. if the switch is close it will be cold hince no hot water from radiator to warm
it may be opening and closeing back should be easy to find im not sure where it is on your car.
go to auto zone look in there chiltons book under cooling diagrams and see where it is loacated

Tracy, Did you replace the thermostat? If it sticks open the thing wil never heat up. I've actually seen these things rot out and fall to pieces. It easy to get to and not too messy. Let me know
